Chevron Phillips Chemical Company L.P. currently has 10 pending office actions within its company patent portfolio in the Chemistry & Materials technology area. These actions are being reviewed by 10 distinct examiners, which means that each official is handling exactly one matter for the company. The prosecution is spread across 6 distinct art units, reflecting a diverse range of chemical and material science applications.
PATEL, SMITA S is the busiest examiner for this portfolio, currently overseeing 1 busiest examiner pending office action. This single action represents a portion of the total 10 pending office actions currently active. Because the workload is perfectly balanced among the 10 distinct examiners, no single examiner's decisions will have a disproportionate impact on the overall portfolio.
For practitioners, the presence of 6 distinct art units suggests that the 10 pending office actions cover a broad technical spectrum. The lack of examiner overlap means that 10 different examination styles must be managed simultaneously. Successfully navigating this portfolio requires a decentralized strategy that addresses the unique requirements of each of the 10 distinct examiners across the 6 distinct art units, ensuring each of the 10 pending office actions is handled independently.
Based on the USPTO statutory response window for each pending office action. 4 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 4 of the docket's apps have a known mailing date.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
| Bucket | Cases |
|---|---|
| §101 + other | 1 (10%) |
| §103 only | 5 (50%) |
| Multi-statute (no §101) | 4 (40%) |
